AUTOMATIC NAIL POLISHING DEVICE The present invention relates to anautomatic nail polishing device, and more particularly to a funnelshapednail polishing device rotatable with a suitable driving means such asmotors.

Finger-nail polishing has hitherto been made by sand paper or the likematerials. This method, however, has disadvantages that it required muchtime and since the polishing materials are not made to match the shapeof finger-nails the surfaces of the finger-nails could not be finishedto form smooth curved configurations.

On the contrary, the present invention employs a replaceablefunnel-shaped member which is lined with buffs on both inner and outercircumferential walls thereof and is mounted on a rotatable supportmember driven by a motor whereby finger-nails can be automatically,speedily and smoothly polished.

Accordingly, an object of the present invention is to provide anautomatic nail polishing device comprising a replaceable funnel-shapedmember lined with buffs on the inner and outer circumferential surfacesthereof and mounted on a rotatable support member driven by a suitabledriving means.

Another object of the present invention is to provide an automatic nailpolishing device for polishing fingernails automatically, speedily andsmoothly.

The present invention will now be explained, by way of example, withreference to the accompanying drawings in which:

FIG. 1 shows a side view of a nail polishing device according to thepresent invention, partly in section;

FIG. 2 shows a plane view of same;

FIG. 3 shows a side view of another embodiment according to the presentinvention, partly in section;

FIG. 4 shows a plane view of a plurality of nail polishing unit devices(4 units) according to the present invention arranged in a casing;

FIG. 5 shows a left side view of same; and

FIG. 6 shows a side view of still another embodiment according to thepresent invention.

Referring to FIGS. 1 and 2, a funnel-shaped member 1, which is made ofsuitable metal or plastic material, has on its inner and outercircumferential walls thereof two linings S and S of coarse and finepolishing buffs respectively. The funnel-shaped member 1 is replaceablyassembled to a rotatable support member 2 by means of a pin 3. Thesupport member 2 has a square slot 4 at the bottom thereof and receivesa spindle 5 connected to any suitable driving means such as motor (notshown).

In operation, when the motor is actuated the support member 2 is rotatedby the spindle 5 thereby to rotate the funnel-shaped member 1 and theuser can polish his finger-nails one by one only by applying same to thematching rotating inner or outer circumferential walls of the member 1.Thus, due to the configurations of the inner and outer walls of thefunnel-shaped member 1 which are well matched to those of finger-nails,polishing may be performed automatically, speedily and smoothly. I

The nail polishing device according to the present invention may bearranged in a casing in units (usually 4) so that more than onefinger-nails may be polished at a time by operating a motor (not shown)through a switch 6.

Further, as shown in FIG. 3, the funnel-shaped member 8 having linings Sand S of coarse and fine polishing buffs on its inner and outercircumferential surfaces respectively may be rotatably mounted on a grip10 by a pin 9 which is connected to one end of a flexible wire shaft 11.The other end of the flexible wire shaft 11 extends vertically throughthe grip 10 and is connected to a motor (not shown) so that thefunnel-shaped member 8 may be rotated on the grip 10 with the rotationof the flexible wire shaft 11. Further, the entire length of the portionof the wire shaft 11 below the bottom end portion of the grip 10 may beencircled in a flexible tube or shield 12 whereby the funnel-shapedmember 8 can be operated at various angles allowable, by grasping byhand the grip 10 with the aid of the flexible tube or shield 12.

Lastly, referring to FIG. 6 which shows still another embodimentaccording to the present invention, there are provided a pair of beams19 and 19' pivotably connected by a hinge (not shown) and extendinglaterally in opposite directions. The beams 19 and 19' may form variousinternal angles downwardly by a locking screw 20 which fixes the beams19 and 19' at a desired angle. Further, at the point of connection and,at the free ends of, the beams 19 and 19' there are provided a centralpulley l7 and a pair of side pulleys 16 and 16' respectively whichlatter are supported by spindles 15 and 15. These pulleys are rotatedwith a pulley 17 attached to a motor M by means of a single belt 18.Now, a pair of funnel-shaped members 13 and 13' having on their innerand outer curved walls linings of fine and coarse polishing buffsrespectively are mounted on the upper surfaces of support members 14 and14' in the like manner as shown in FIG. 1. The support members 14 and 14receive the spindles l5 and 15' of the said pulleys 16 and 16' and arerotated therewith.

In this mechanism, it will be seen that since the angle of the two beams19 and 19 can be adjusted by the lockking screw 20 the user can polishhis finger-nails at the most desirable angle for his posture.

Thus, the nail polishing device according to the present invention hasthe advantages that the nail of any finger may be polished on the curvedinner and outer circumferential walls of the funnel-shaped member of thedevice according to its configuration and it is especially suitable forpolishing the corners of a finger-nail at the outer edge of thefunnel-shaped member and further, since the funnel-shaped member islined with both fine and coarse polishing buffs an overall and completepolishing may be performed by this single device.
